Well I just signed up for PayPal Mobile. It works like a charm! First of all, it has awsome security. I have my cell phone number on my PayPal account. In order for me to gain access via phone to my PayPal account, I must be making the call from my cell phone. I tried accessing my account from my home phone, and it would not let me. When you call up the mobile service, you have two choices. Those two are either check your balance, or send money. I will mostly use PayPal Mobile for checking my balance when I am out and about and away from my computer. For anyone that has a PayPal account, I highly recommend signing up for PayPal Mobile.
